Abrasion resistance of high-strength concrete in hydraulic structures
This paper presents the results of the examinations of abrasive wear of the nine types of high-strength concrete (HSC) with compressive strength of 75-120 MPa. The mixes were made with: Portland cement CEM I 42.5R, CEM I 52.5R and blast-furnace cement CEM IIIA 42.5, basalt aggregate with added superplasticizers and silica fume. The mixes contained of steel fiber: 30 and 50 mm length and aspect ratios of 60 and 50 and polypropylene fiber as a reinforcement. Two types of concrete were modified with latex. For the examinations of the abrasive resistance of HSC, the ASTM C 1138 (standard test method for abrasion resistance of concrete) method was selected. This paper contains the results of studies on the abrasive resistance of HSC in dependency of the compression strength, modulus of elasticity, fiber material and dimensions. The curves of wear of the examined concrete and the mean velocity of wear were determined. The obtained courses of wear were analyzed and compared with the results of examinations of standard concrete.
